UNITED STATES PATENT OFFICE. HARLEY sMi TH, oF BUFFALO, MISSOURI.` I I' COAlN-COANTROLLED SHOIEPOILISHlNG IVIACI'HNE-n Patent-.ed oct. so, I190e.

Application led November 12, 1904. Serial lo. 282,505.

Be a known that i, HARLEY Smm, a Citi- .zen of the United States, residing at Buffalo,

'in the county of Dallas and State of Missouri,

have invented new and usefullmprovements in Coin-Controlled Shoe-Polishing Machines, of which the following is a specification.

This invention relates to a shoe-.polishing machine, land has for itsobjects to produce a comparatively simple inexpensive device of this character wherein the o erations of applying ,the blacking to and vpolishing the shoes will be automatically performed, and one in which the introduction of a coin into the machine will set the operating mechanism and maintain the same in such condition fully hereinafter described.

until the completion of the polishing action, whereupon the coin will be released and permitted to enter the coin-receptacle and the machine rendered inoperative until'the introduction of a second coin.

A further object of the invention is to provide' a mechanism which will be automaticallyl shifted for alternately operating the blacking applying and. polishingl brushes and one wherein the brushes ma be readily and" accuratelyadjusted to co orm to the varying sizes of shoes o erated upon.

A further object of t e inventlon is to provide a locking mechanism which at the completion of each step of the polishing operation will automatically throw the motor lout of o eration and simultaneously actuate a brea g mechanism for checking the momentum of the power-shaft to thus instantaneously stop the machine.

A further object is to provide an improved mechanism for feedingl the blacking to the black' -applying brush and one wherein spattenng of the blacking will be prevented and the surplus blacking returned to the reservoir. l

With these and other objects -in view the invention .comprises the novel features of construction and combination of parts more .In the accompan drawings, F` r6.1 is a longitudinal sectional elevation o a machine embodying the invention. 2 is a horizontal section taken on the line2 2 of Fig.' 1 with arts ofthe mechanism omitted.

Referring to the drawings, 1 designates a casing divided into an upperI compartment2 ig.`9 is 'a similar view showing.

4view of the rock-shaft carrying the valve for and a lower compartment 3 by means of a 4 horizontal partition or platform 4 approprialtely s aced from the bottom 5 of the casing, t ere '7S eing sustained within the com artment 2 beneath and suitably remote om,

the top 6 of the casing a` horizontal supportin -frame 7.

' ustained upon the'frame 7 is an electric' motor 8, provided with and adapted for driv- 1 mg a worm-shaft 9, in mesh with a wormear 10, fixed upon a drive-shaft 1 1, journale for rotation in suitable bearingsr 12 and in turn carryinga vorm 13, in mesh with a horizontal wormear 14, journaled for rotation upon a vertica shaft or axle 15, there bein arranged upon the ends of the shaft 11 cran -arms 16 and upon the worm-gear 14 a series of fixed vertically-uprising pins or abutments 17, 18, 19, and 20, arranged at spaced intervals around and adjacent the eriphery of theI gear and of varying lengt for a purposev Pivoted at their' upper ends to the top 6 of the casing is a air of spaced operating-levers 21 22, of which the lever 21 is pivoted4 at its lower en'd to a polis j brush or brushes 23, while the lever 22 is'in 'ke manner pivot-- ed at its lower end to blacking-appl brushes 24, these levers being connected, re-

As A tively, with the crank-arms 16 by means o links 25, pivotally connected with the crank-arms and with the levers at points between the ends of the latter, whereb when the shaft 11 is rotated the brushes wi l be reciprocated in a horizontal plane back and `forth through openings 26 provided in the front wall 27 of the casing foot-rests 28 29, mounted upon the' partition 4, which for this purpose projects beyond the front wall of the casing. f

and over suitable The sets of brushes are identical in construction and operation and each includes a4 '34, provided in and extending transversely of the platform, whereby the rods, and conse- Y quently the brushes 30, may be adjusted toward and from each other, the rear ends of the brushes being for this purpose connected 4 by means of a rod 35, fixed to one of the brushes and telescoping with a tube 36, 'fixed to the other, this rod and tube serving as a bearing for the lower end of the operating lever which reciprocates the brushes. llaeh set of brushes also includes a top brush 37, pivoted for vertical swinging movement upon the connection y 36 and disposed with its bristles projecting inward between the bristles of the brushes 30, it being noted that the outer or forward ends of all the brushes are curved outwardly to permit free entrance of a -shoe between them and that the side brushes 30 are provided at their forward ends each with a series of vertically-superposed spring-sections 38, pivoted, as at 39, to the b ody of the brush and adapted for independent movement to conform to the irregular surface of the shoe.

Pivoted, as at 40, to the inner face of the front Wall 27 of the casing is a lever 41, en-

i, gaged at its upper end with a segmental guide-slot 42 .and pivotally connected at its ower end with a crank-arm 43, fixed upon a rock-shaft 44, journaled beneath the platform 4 and fixedly carrying normally vertical crank arms or heads 45, connected by a system of links 46 with the movable brackets 33, the links being so arranged that when the shaft 44 is rocked in one direction the guides 32 and brushes 3() will be moved toward each other and when the shaft is rocked in the reverse direction said parts will be'moved away from each other to thus adjust the brushes for shoes of varyingsizes, as heretofore mentioned, there being provided upon the upper end of the lever 41. a pointer 47, designed to travel over a scale 48, arranged on the face of the casing and graduated to indicate shoes of different sizes.

The crank-arms 16 are fixed, respectivel to clutchr members or heads 49 50, loosely mounted upon the shaft l 1, to which is keyed for longitudinal sliding movement, by means of feathers 51, coperating clutch members or heads 52 53, adapted for rotation with the shaft and connected for simultaneous movement by means of a yoke 54, having a fixed v pin 55 engaged with the rear slotted end 0f a shifting lever 56, pivoted at 56 between its ends to a portion of the frame 7 and pivotally connected at its'forward end with a link 57, which in turn connects the rear ends of a pair of pivoted bell-crank levers 58 58, there being also pivoted at 58 between its ends to the frame and in rear of the levers 58 581a motor-controlling lever 59, carrying at on'e end a catch 6() and connected at its other end with a primary sliding bar or member 61, mounted for reciprocation in suitable bearings upon the frame 7 and in longitudinal alinement with a secondary sliding bar o1` member 62, .also mounted in bearings on the frame, the member 61 being connected at its rear end with a movable brake member or beam 63, adapted for movement into and out ol' the path of rotation ol' the crank-arms i6, and the adjacent ends of thel bars 6l 62 being normally spaced and disposed at opposite sides ol" the lower end of a coin chute or`way 64, projecting at its upper end through the front wall of the casing and communicating adjacent to its upper end, by means ol' a branch duct 65, with a receptacle 66 .and at its lower end with a receptacle 67. Attention is here directed to the fact that the clmte 64 is of a size to receive nickels, while the branch duct 65 connnuuicattes with the chute 64 by a slot of a size to receive pennies, whereby should the latter coins be introduced into the machine they will pass through the duct 65 into the receptacle 66, while nickels will continue downward through the chute 64 and be received initially between the spaced ends of the bars 61 62 for a purpose which will be more fully hereinafter explained.

Pivot-ed between its ends, as at 68, to the rear wall of the casing l is a lever 69, connected at its up er end` by means of a .rigid elcment or linff. 70, with the secondary slidin member 62 and adjacent its lower end wit the casing 1 by means of a normall contracted spring 71, there being provide upon the lower end of the lever, a pair of oppositely-extending engaging portions or fingers 72, adapted for engagement by bell-crank levers 73, pivoted, respectively, upon the rear endsof a pair of horizontal rlgid elements or links 74, arran ed within the compartment 3 and connecte at their forward ends with bell-cranks 75, pivoted, respectively, lbeneath the shoe-rests 28 29 and carrying at the free ends of their horizontal arms vertically-movable depressible members or treadles 76, projecting upwardly through the foot-rests, it being a parent that when one of the treadles 76 1s epressed the lower end of the lever 69 will, through the medium of the bell-cranks 75 and 73 and connectinglink 74, be moved forward against the action of the spring 71, thereby causing said lever through the medium of the link to impart a rearward slidin movement to the bar 62,

IOO

and that when t e lower end of the lever 13o iss-1,18?

. sto or abutment 77, fixed upon the bottom o -the casing, the spring 71 will act to rehur turn. the lever and sllde 62 to normal-posi-- tion. c i Arranged within the compartment 3 is a receptacle 78, designed to receive liquid blacking, which 'will distributed, by means of vertical.y endless distributing members A or belts 79, onto the brushes and by an in- -clined distributing member orv belt 80 to the brush 37 of the set of brushes 24. These belts are arranged fortravel upon suitable pulleys on a shaft 81 within the receptacle 78 and on ulleysf arranged on shafts 82 83, jplurnale respectively, beneath and within t, e

l,the

gath of movement of brush 37 and above rushes 30, the shaft v83 being driven to impart motion to all ofthe distributing-belts by means of a belt 84, arran ed for travel on a pulley 85, fixed upon the c utch member or head 50. As the brushes 30 are reciprocated they move in contact with the belts 79, and in order to prevent the blackin from vspattering I arrange upon the inner si e faces .of the beltsl 'and extendinglongitudinally thereof vertical guards or shields 86, composed, preferably, of sheet metal and having grooves or channels 87, in'which the belts seat, these lchannels being "adapted to, re-

ceive and return the surplus blacking tol the -rece tacle, while on 'the' lower ends of the shie ds 86 are small rollers 88, between which the flights of the belts'pass to regulate the quantity' of blacking carried upward thereby. Attached to the casing is a bracket' 89, to the outerlendof which is pivoted on a vertical pintle 90 a series of three horizontal tripping members or levers 91 92 93, arranged 1n vertically-spaced relation one above another and engaged individually by springs 94, in

turn connected with a part 94 of the bracket 89, these levers being adapted for forward lmovement against the action of the s rings `by meansof the pins 17 to 20, carried y the gear\ 14, attention being directed to the fact that the pins 17 and l19 are of equal length and of such height as to act only upon the lowermost lever 91, while the pin 18 is of greater length to act upon-the levers 91 and 4 92, and the pin' 20 of such length as to engage and operate all three of the levers, Connected. with the lowermost lever 91 is a longitudinally-movable. rod or element 95, carrying at its outeror forward end a ivoted latch 96, adapted for enga ement wit the catch on the lever 59 an having anupwardly-projecting arm or portion 97, designed to contact with a suitable stop 98 for tri ping the latch to'disengage it from the cate as illustrated in Fig.` 9, while the intermediate lever 92 h as connected therewith therear end of a rod or element 99,.carryinfgnat its forward end an engaging portion o r .tinuous Athe o 'erator places one foot upon the rest 29, there v depressing the adjacent treadle 76 ger 100, adapted Afor en agement with thelfree arm of either of the be l-crank levers 58, 58, there being attached to the uppermost lever 93 a rod or link 101, engaged at its forward end with a 4crank-arm 102, fixed upon'one end of a rockshaft 103, which is `fixedly engaged with a flap valve or closure 104, arranged beneath and for normally closing the lower end of the vchute 64. 1 1

In practice when a coin of proper denomi- 'nation is entered into the chute 64 it travels downward through the latter and lodgesV upon the valve 104 between the members 61 62, thus serving to bridge the space between said members and render them in effect con- The coin having been deposited,

and, through the medium of the intermediate connections', moving the member 62 rearward, as heretofore explained, this movement of the member 62 serving, through the medium of the coin, to impart a similar movement to the member 61 for actuatin the brake 63 to release the crank-arms'l an simultaneously bringing suitable contacts 105 on the member 61 to position for completing the circuit and starting the motor8 to drive the shaft 1]. At the beginning of the rotation of sha-ft 11 the clutches 52 and 53 are shifted to the right, as illustrated in Fig. 2, whereby motion will be imparted to the blacking-applying mechanism and the polishing mechanism will 'for the time bemg be inactive, while at the same time motion will be imparted tothe worm-gear 14 from the worm 13 on the shaft. The parts are thus driven for a suflicient length of time to apply the blacking to one shoe and until one of the short pins 17 comes incontact with the lowermost lever 91, thereby moving said lever forward and engagin the latch 96 with IOO the catch 60, whereupon t e lever will when for applying blacking to the other shoe,l

IIO

whereupon the pin 18, of intermediate length,

comes into contact with and actuates levers 91-and 92,l thereby stopping the machine, as

heretofore explained, and at the same time enga 'ng the catch 100 at the end of the rod 99.W1th the lever 58, and when the levers 91 and 92 are released by the pin 18 the lever 58 will be actuated for operatinr lever 56 to shift the clutch mechanism to thecleft, (see Fi 2 thereby throwing ,the blackingappllying i mechanism out of operation and bringing into action the polishing mechanism, it being understood that u onithe next ,operation of the rod 9.9 throug thev lever 92 -it Will act u on the lever 58BL Vvfor im arting a reverse s 4iftlng movement to the c utch mechanism.

The operator now places one foot upon the rest 28, which again operates the sliding members -for starting the machine and cans ing a continuous operation-of the. polishingbrushes until the second short pin lll-. contacts with and `actuates the lowermost lever 91 to again stop the machine, as heretofore explained, to permit the operator to place ot er foot in position upon the rest 28, thereby again startin the machine, which continues to run unti the second shoe is polished and the longest pin 20 contacts with and actuates all of the levers 91 92 93?.v Upon movement of all the levers through the medium of the pin 20 vthe machine will be stopped, the .clutch members shifted from left to rigrt, and the link 101 actuated for. operating t e 104 andpermit the coin to drop into the receptacle 67, it being apparent that after the com has .drop ed the member 62 may be n moved, throng Ithe medium of the treadles 7.6 and intermediateconnections, Without afecting the driving mechanism of the ma-` H thus fully described the invention,

what is claimed as new is- 1. In a .device ofthe class described, a

i blacking-applying element, a polishing clement, a drive-shaft, operative connections between the drive-shaft and elements for operating .the latter independently, a clutch member for connecting either of the elements with the shaft and means Jfor `automatically .Shifting the .cl
